The Unitrac was a good arm for higher compliance cartridges. I think it was designed with the Shure V15 and comparable ADC and Sonus cartridges in mind. I wouldn't really recommend it with low compliance moving coils.
RE:Magnepan Unitrac arm
Hello, I am new to the threads but I know there is lots of knowledge here so I hope someone can help? I while back I bought a Unitrac arm and have since mounted it on my Micro Seiki DDX1000 tt. I have been collecting vintage MC cartridges for our new audio club, so I am mounting 3 arms so that we can switch cartridges .I thought the VTA on the fly adjustment of the Unitrac made it a great canidate for this reason. I dont have the proper alignment protractor so heres where I need help? Is there anyway I can use another protractor? I have a formula 4 one? Can anybody send me a scan of theirs as I would pay for your time? Our their any other set up tricks with this arm I need to know? Will it even work for MC cartridges or am I waisting my time trying? I dont have the cartridge set up rig but I should be able to eyeball the overhang? Of course on my tt the arm had to be mounted at an unusual angle and not the normal 57 degrees if you know what I mean. Any help at all on set up would be great as I haven' t mounted a cartridge yet as I have to track down some lead pellets first. Please advise if you can? Thanks and regards Daren
